Excel plays a vital role in data analysis and enables its users to make informed decisions by analyzing their data in Excel. Quartile is one of the statistical measures in Excel that provides the central tendency of the data set by dividing the data into four sets. However, sometimes it becomes challenging to understand the functionality and significance of the quartile functions and formula. The article will empower you to use the quartile function easily through a detailed step-by-step guide.
What are Quartiles?
Quartiles are a function in Excel that is used to divide a data set into four equal parts, each containing an equal number of data points. Quartiles help you to understand the variability and distribution of the data. In addition, quartiles provide valuable insights into the spread and central tendency of the data. The four quarters that divide a data set into quartiles are:
Q1 = The lowest 25% of numbers.
Q2 = The next lowest 25% of numbers
Q3 = The second highest 25% of numbers
Q4 = The highest 25% of numbers.
For Example, if you want to calculate the Q1, the formula that you use will be:
=QUARTILE(range_of_data , 1)
How to Use Quartiles in Excel:
Way 1: Using basic Quartile function:
Step 1: Open the Excel workbook and enter your data set in a column.
Step 2: Type the QUARTILE function in an empty cell. For example, if you want to find Q1, use the formula: =QUARTILE(range_of_data, 1)
Step 3: Press enter on your keyboard, and the result of the quartile will be displayed in the cell.
Way 2: Using Quartile.INC and Quartile.EXC function:
Step 1: Open the Excel workbook and enter your data set in a column.
Step 2: Type the quartile function: =QUARTILE.INC where INC stands for "Inclusive," or Type the quartile function: =QUARTILE.EXC, where EXC displays exclusive results.
Step 3: Select your required quartile and press enter on your keyboard to see the result.

FAQs
1. How do I calculate quartiles in Excel?
You can use the QUARTILE() function to find quartiles in Excel. The function will divide your data set into four different sections and provide the results accordingly.
2. What is the difference between the QUARTILE.INC and QUARTILE.EXC functions?
Both INC and EXC functions are used to find the quartile of a data set. There is a slight difference in the logic of both formulas. The QUARTILE.INC function calculates the value at a given percentile of a dataset using the inclusive method. Whereas the QUARTILE.EXC function determines the value at a given percentile of a dataset using the exclusive method.
3. How do quartiles help identify outliers in a dataset?
Any value that is 1.5 x IQR greater than the third quartile is designated as an outlier, and any value that is 1.5 x IQR less than the first quartile is also designated as an outlier.
Summary
The article explains how to find quartiles in Excel, which are statistical measures used to divide a data set into four equal parts. It provides step-by-step instructions on calculating quartiles by using the basic QUARTILE function and using the QUARTILE.INC and QUARTILE.EXC functions, respectively. Overall, the article aims to empower users to gain valuable insights into their data's distribution and variability by effectively utilizing quartiles in Excel and WPS Office.
